Nick Cannon Hospitalized for 'Kidney Failure'

Nick Cannon has been hospitalized in Aspen, Colo., with what his wife Mariah Carey is calling "mild kidney failure."

"Please pray for Nick as he's fighting to recover from a mild kidney failure. #mybraveman," the singer wrote on Twitter Wednesday, alongside a photo of her helping Cannon take a drink in his hospital bed.

Carey later elaborated in a post on her website: "Last year it was me attached to the machines (after having dembabies) and Nick was there with me through it, and now here we are."

She added: "We're trying to be as festive as possible under the circumstances but please keep Nick in your thoughts because this is very painful. ... I'm not trying to make light out of the situation because it's a serious moment that's very tough on all of us so please keep us and our family in your prayers."
